Abstract: This invention concerns a method for determining upstream interference and is connected to the allocation of resources in mobile radio systems comprising a number of base stations with associated coverage areas and mobile stations. According to the invention the level of interference in a coverage area with regard to interference from mobile stations in another coverage area is determined by the measured/calculated field strength values related to geographical co-ordinates in the respective coverage areas for the interfering mobile station being represented by a static model. The values of the interference field strength can either be represented in table form and a uniform indication of all the values in the table can be carried out, or they can be represented by a distribution function, preferably with logarithmically normal distribution. <IMAGE>
